Hello, I already put the SZL with HBA and vibration support, I also put the switches for activation of FCW and LDW.  After placing and erasing the errors the FCW has been running though every time I turn on the car says it has malfunction in the collision and pedestrian detection warning but then erases and works.  but when I try to activate the error LDW and it does not work is still missing the vibratory module?  I barely start the car for a few seconds and crash.  and pedestrian detection I can't activate says it doesn't work.

Have you run the extra wires from the SZL to a power and ground source?
